Blocked Vent/Spill Switch Operation: During each run cycle, the BV contacts will be checked beginning
30 seconds after ignition. If the BV contacts open (indicating the spill switch has detected a blocked vent),
the control will shut down the burner. The control will either recycle the burner or will go immediately into
Lockout dependent on the Allowed Recycle setting. The spill switch must be closed within 2 seconds on a
call for heat. If not, it will retry 2 times before control goes into lockout.
NOTE: If using a manual reset blocked vent spill switch, the control will lock out with the display reading BV
Switch Open.
